Approved by the competition committee this week 1) in the case where the defensive team was violating the anti-shift rules (three fielders on either side of 2B or an IF'er with feet on the OF grass) - Previously, if an infielder was caught violating the rule the batting team could accept the result of the play or have the hitter be awarded an automatic ball. Under the new rules, the batting team may accept the result of the play or the batter will be granted a free base (enabling any other runners to advance one base) if there is a violation and the violating player was the first to touch the ball in play. In such a scenario, the violating player would be charged an error and no at-bat would be registered for the batter. 2)The second rule change involves the rare practice of running through a base other than first base on a force play. For example, if there are runners on first and third with two out and a ball is hit on the ground, the runner going to second base might opt to run straight through the bag rather than sliding in the hope that he'd get there faster and beat the throw. In the past, if a runner was called out at second in this scenario, and upon review a replay official found that he actually did beat the throw before going past the bag, the umpires would have to ignore that the runner overran the base and place him on second. The new rule change gives umpires the power to call the trail runner out for abandonment of second base even if he beat the throw. He is considered to have abandoned the bag as soon as both feet land on the other side of the base. In that case, whether the runner at third scores or not will depend on whether he touched home plate before or after the runner at second was ruled to have abandoned second base. On the first one: I don't remember an illegal defense call made last year (do they still even call it in the NBA?). But, if the call is made and the illegally slotted IF is the first to touch the batted ball I can see the wisdom in the free base option. A bigger penalty makes fudging on the rules less tempting. 'Hey, I'll cheat onto the OF grass and if I can throw him out on a grounder good for us ... and if they catch me it's just Ball One so no biggie!' On the second: the way it reads I think this is only applicable if the runner over-runs 2nd or 3rd and is ruled safe only after replay review, iow, after the fact. So it's kind of a rarity on top of a rarity. But some runners were using the over-run as a kind of strategy which was risky, but kind of cool at the same time. ex: Runners on 1st & 3rd/1 out. Runner from 1st runs through 2nd because it gets him to the base quicker, sometimes quickly enough to beat the force play. So now if the batter is out at 1st on the replay, it's only the 2nd out and the run from 3rd scores because the force is now off even if the defense eventually puts the other runner out between 2nd & 3rd. And maybe the runner himself winds up safe at either 2nd or 3rd if the defense doesn't play it correctly. So, smart strategy by the runner(s) if you can pull it off! But I guess the purpose here is to Not reward guys who were initially called out via a force. He was called out therefore him leaving the base was abandonment so he's out anyway even if replay later rules otherwise. So the real culprit here is the limitations of replay and the idea that incorrect calls can all get fixed after the fact and the situation will be put back to how it 'would have been' with a correct call. https://www.mlb.com/news/mlb-shift-baserunning-rules-changes-2025https://www.mlb.com/news/mlb-shift-baserunning-rules-changes-2025
